Blade Lead
Bandsaw blades may wander off the cut line
when sawing, as shown in Figure 70. This is
called blade lead. Blade lead is usually caused by
too fast of a feed rate, a dull or abused blade, or
improper tension. If your blade is sharp/undam-
aged and you still have blade lead, perform the
following procedures.

line of cut.
Correcting Blade Lead
1.
Use less pressure when feeding the workpiece
through the cut.
2.
Check that the miter slot and fence are paral-
lel to the blade line, and correct if necessary
(See Aligning Table, Page 29 and Aligning
Fence, Page 30).
3.
Check for proper blade tension. If the blade
tension is correct and it is not convenient to
replace the blade, compensate for lead by
skewing the fence or shifting the table.
To skew your fence:
1.
Cut a piece of scrap wood approximately
thick x 3" wide x 17" long. On a wide face of
the board, draw a straight line parallel to the
long edge.
-58-
2.
Slide the bandsaw fence out of the way and
cut halfway through the board on the line by
pushing it into the blade. Turn the bandsaw
OFF and wait for the blade to stop.
3.
Clamp the board to the bandsaw table with-
out moving it. Now slide the fence over to
the board so it barely touches one end of the
board.
4.
Loosen the three cap screws that secure the
fence rail to the underside of the table (see
Page 31).
5.
Skew the fence so it is parallel to the edge of
the scrap piece.
6.
While maintaining the skew, tighten the cap
screws loosened in Step 4.
7.
Make a few cuts using the fence. If the fence
still does not seem parallel to the blade,
repeat Steps 1–6 until the blade and fence
are parallel with each other.
To shift the table:
1.
On a scrap piece of wood, mark a line that is
perpendicular to the front edge.
2.
Cut halfway through the board on the line by
pushing it into the blade.
3.
Turn the bandsaw OFF and wait for the blade
to stop.
4.
Loosen the four cap screws that mount the
table to the trunnion. Shift the table to com-
pensate for the blade lead, then retighten the
cap screws.
5.
Repeat Steps 1–4 until the blade cuts straight.
